| Of the 2,000-plus minerals that form good crystals, most never produce large ones. These beautiful tiny yellow crystals are Wulfenite. They are quite perfect, the color is vivid, and the artistry of the composition exquisite. From the gem and mineral collection of the Smithsonian's National Museum of Natural History. |
